Carrying a coffin with others is read as sharing the weight of an ending. Dream books see the pallbearer as duty, solidarity and helping something be laid to rest with dignity.
Does the traditional reading fit your dream, or did it mean something else to you?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
